Endocrinologist Dr. Natalia Novikova pointed out that "drinking water in the morning activates the digestive system and stimulates the production of necessary enzymes." In an interview with the Russian news agency Novosti, she stated, "Everyone should realize that this is essential. Therefore, one should drink water in the morning, as it acts as a trigger for the digestive system. During sleep, enzymes remain in the canals, so they need to be stimulated to work, and for that, one should drink water, which begins to mobilize them. After that, a person has breakfast, and the digestive system starts to secrete new enzymes to efficiently digest the food." The doctor advises the necessity of drinking water in the morning from childhood and recommends drinking two liters of water a day, without counting juices, tea, coffee, soup, and others.
